Easy to use light-weight command line option parsing tool for C++

Option Parser

Note: this project is still work in progress.

Features

• Argument parsing
• Argument checking
• Default value
• Variable binding

How to use:

1. Initialize OptionParser:

    OptionParser op;

2. Initialize your options using the following parameters: -names -> string vector -arg -> possible values are: -OptionArg::NONE -> argument won't be taken even if it's provided -OptionArg::OPT -> argument is optional -OptionArg::REQ -> argument is required -description (optional) -> string describing the option Example:

auto xOpt = Option<int>({"x", "set-x"}, OptionArg::OPT, "set variable x");

3. Add your options:

OptionParser op;
auto xOpt = Option<int>({"x", "set-x"}, OptionArg::OPT, "set variable x");
op.AddOption(&xOpt);

4. Parse

OptionParser op;
auto xOpt = Option<int>({"x", "set-x"}, OptionArg::OPT, "set variable x");
op.AddOption(&xOpt);
op.Parse();

5. Retrieve argument

OptionParser op;
auto xOpt = Option<int>({"x", "set-x"}, OptionArg::OPT, "set variable x");
op.AddOption(&xOpt);
op.Parse();

int x = xOpt.Value();

Testing

GoogleTest is required for building tests, it shuold be located in the lib folder. Install:

cd build
git clone https://github.com/google/googletest/
